LAS VEGAS (AP) - Brock Lesnar defended his heavyweight title in his uniquely brutish style at UFC 100 Saturday night, capping the sport's landmark weekend with a second-round stoppage of Frank Mir.
Georges St. Pierre defended his welterweight title with a showcase of his inimitably well-rounded mixed martial arts skills in an unanimous decision over Thiago Alves, while Dan Henderson knocked out Michael Bisping with a single punch in a middleweight upset as the UFC rolled its odometer into triple digits on a celebratory night for the proliferating sport.
Lesnar (4-1) ended the main event with a relentless series of right hands into the face of Mir, who handed Lesnar his only loss nearly 18 months ago.
Lesnar, a hulking former pro wrestler with a mercurial temperament, then taunted his opponent while Mir still was on the ground. He added a two-handed obscene gesture to the booing sellout crowd at the Mandalay Bay Events Center, putting a strange end on a celebratory event for the league.
